Not exactly aimed at language keywords (although it is aimed at the language designers who decided abbreviations in keywords are acceptable):
I hate abbreviations in source code so fucking much. Reading is more of software engineering than writing. If you cannot be bothered to type a whole word because typing is hard for you, find a different job. Do not force others to engage in mental gymnastics to understand what the fuck a variable or function is supposed to mean.
